TEMPERATURE-REGULATOR- Specification of Letters Patent.-

Patented April 9, 1907.-

Application filed May18,l906.- Serial No. 317,446.

which is quickly responsive to varying-conditions and will act to control the temperature by the opening or closing of a draft-door, flue, the operation of a steam-valve, or other well-known means whereby the temperature of a room or apartment is regulated.

A further object of the invention is to pro- 'vide a device of this character which may be used both as a temperature-regulator and as a safety device for application to steam or hot-water heating systems. I

A still further object of. the invention is to provide .a thermostaticall -controlled temperature-regulator in Whic the Work of op-' erating the damper or other temperaturecontrolling means is accomplished by the wei ht or pressure of a fluid, the flow of the flui .being placed under the control of an electro-magnetically-actuated valve.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction' and arran ement of parts hereinafter fully described, companying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the' spirit orsacrificing any of the advanta es of the invention.

In t e accompanying drawings, Figure :1 is an elevation of a temperature-regulating device constructed in accordance with the'invention, showing the same as applied to a boiler and the regulating device being attached; to and controlling the opening and closing-ofa damper. Fig. 2 is a side elevation of the electromagnetically actuated valve. Fig. 3 is a transverse sectional view of the valve-casing. Fig. 4 is a similar view of the damper-actuating device.

Similar numerals of reference areemployed to indicate, corresponding parts throughout the several figures of the drawings.

In carrying out the invention a thermoillustrated in the ac stat 10, formed of any suitable material, is

placed at any desired pointas, for instance,

in ,a room or apartment which is heated by steam, hot water, or air received frpma heater 11, which may be located in the'cellar or at any other convenient point.

Arranged above the heater or boiler 11 is a casing 1.5, containing two spaced diaphragms 16 and 17, which are preferably formed of some yieldable or elastic material, the upper of these diaphragms carrying a stem 18, Whichis connected to a lever 19, that is pivoted to a small post or bracket'20, carried by the casing, and is guided by'a slotted post 21, also carried by the casing. This lever is connected to a temperature-controlling means, which in the presentinstance takes the form of a damper (Z. By opening the damper the temperature may be raised or lowered in accordance with the location of said. damdper but in the present instance it is presume that the opening of the damper will reduce the draft through the combustible material on the grate, and therefore lower the fire, while the closing of the damper will result in increased supply of air to the combustible material and the raising of the temperature.

At one side ofthe casing 15 or at any other convenient point is arranged a valvecasing 23, one end of which is connected to the casing 15 by a pipe 24, while the opposite .end of said casing has an inlet-pipe 25, leading from any source of fluid-pressure supplyas, for instance, the water-pipe.

The casing is provided with a partition 26, having an opening that is tapered to form a seat for a Valve 27, which may beremoved from position b' unscrewing a suitable pin 28 in the upper portion of the casing, sai plug being provi ed in the present instance with a depending tubular guide 29 to re-' ceive the upper portion of the valve-stem. The lower portion 'of the casing is provided with a discharge-port '30-,the mouth of which is tapered to form a seat for the valve 31, which is also accessible on suitable plug 32. The two valvesare operated by a lever 33, that is secured to a rockshaft 34, that extends out through one'side of the casing, stuffingsbox or gland 35', To the endvof the stem is secured a rocker-arm 37, carrying an armature 38,, that isdisposed between the opposite1 pole-pieces of a pair of 'electromagnets 39 an preferably through a small TOO the removal of a phragm 17 to The thermostatic element 10 is connected and the fluid under pressure entering through pipe 25 passes the valve and. through the casing, running through pipe 24 to the casing 15, where it acts upon diaphragm 17, raising the latter, and this movement is transmitted to the'lever 19, with the result of opening the damper, and thus decreasing the temperature. The damper will remain in this position until the temperature decreases, whereupon the thermostat may move into engagement with the contact 47, closing a circuit through the electromagnet 40 and moving the valve to the opposite position-that is to say, closing the inlet-valve 27 and openingthe discharge-valve 31, so that the water or other fluid is allowed to escape through the casing 15, through the pipe 24 and casing 23, to discharge-port 30. This allows the diadescend and permits the closing of the damper, with the result of increasing the temperature.

The lower'portion of the casing 15 is connected to the steam-space of the boiler by a pipe 50, and in case the thermostat fails to respond to increase in temperature from any cause and there is likelihood of dangerous steam-pressure in the boiler the steam passing upward through a pipe will act on the lower diaphragm 16, and abutton'51, carried by this diaphragm, will. engage a button 52, carried by the upper diaphragm, moving the latter up and transmitting movement to the lever 19 and to the damper, thusreducing the steam-pressure.

- It will be understood that the apparatus forming the subject of the present invention may be applied to and used in connection with any temperature-regulating -device such, for instance, as a window or ventilator, a steam-valve, hot-air register valve, damper, or other known means by which temperature may be regulated.

Iclaim In apparatus of the class described, the combination with a steam-boiler, of a temperature-regulating member, a casing having a pair of spaced flexible diaphragms, the adjacent faces of which are provided with buttons or blocks, a pipe connecting the lower portion of the casing to the steam-space of the boiler, a stem extending from the upper diaphragm, a lever connected to the stem and to the teniperature-regulating member, a valve-chamber, a ported partition in said chamber, there being a discharge-port leading from said valve-chamber, a pair of valves controlling the ports, -and a lever for operating both valves, a rock-shaft carrying the lever and extending out through the wall of the chamber, an armature hung on the rockshatt, a pair of .electromagnets between which the armature is arranged, electromagnetic connections between the thermostat and the electromagnets, afluid-pressurcsupply pipe connected to the valve-chamber,

and a connecting-pipe leading from said chamber to the casing at a point between the two diaphragms.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence, of two witnesses.v
